Description

Technical Field

[0001] This invention belongs to the field of mixture extraction technology, and particularly relates to a centrifugal extraction device. Background Technology

[0002] During the centrifugal extraction of the mixture, a washing solution needs to be added. The washing water can effectively dissolve and remove water-soluble impurities such as residual acids, alkalis, salts and polar by-products in the mixture, thus preventing these substances from affecting subsequent purification steps or product purity. However, if the washing water is directly discharged into the centrifuge and comes into direct contact with the mixture, it is easy to cause the formation of an emulsion layer inside the drum. A structure to avoid the formation of an emulsion layer inside the centrifuge is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a centrifugal extraction device that solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal extraction device, comprising a storage cylinder, a plurality of storage cylinders symmetrically arranged in a mixing tank, and longitudinal through grooves symmetrically provided on the storage cylinders, with corresponding sealing plates provided on the through grooves, the sealing plates being rotatably connected to the storage cylinders and tightly fitted to the storage cylinders, and a stirring plate being rotatably connected to the bottom of the mixing tank; further comprising a limiting component for causing the storage cylinders and sealing plates to rotate relative to each other; and a feeding component for adding solid demulsifier into the storage cylinders.

[0005] Beneficial effects

[0006] This invention provides a centrifugal extraction device, which has the following advantages compared with the prior art:

[0007] The user adds solid demulsifier to the corresponding storage cylinder through the flared tube. Because the sealing plate blocks the grooves on both sides of the storage cylinder, the demulsifier accumulates inside. When the preset amount of demulsifier is reached, the user rotates the cover plate, causing the guide tube to rotate synchronously around the mixing tank until the positioning rod is aligned with the second groove on the indicator panel. At this point, the flared tube is above the second storage cylinder. Because the outer diameter of the guide tube is smaller than the inner diameter of the through groove, it effectively prevents the demulsifier from falling outside the storage cylinder when poured. The user then repeats this process until the same amount of demulsifier is added to all storage cylinders. At this point, the user can pour washing liquid into the mixing tank through the flow tube on one side. When the washing liquid is level with the top of the storage cylinder, the user can close the valve on the flow tube. The user can then start motor A, causing the connecting block fixedly connected to the output shaft of motor A to rotate in a circular motion within the mixing tank. Because the gear ring meshes with the gear, the rotation of the gear ring drives the gear to rotate at a constant speed. This causes the storage cylinder fixedly connected to the inner wall to rotate relative to the sealing plate, causing the grooves on both sides of the storage cylinder to move out of the sealing area of ​​the sealing plate. At this point, the demulsifier in the storage cylinder begins to contact the washing liquid, thus preparing a mixture with a certain concentration to prevent the washing liquid from forming an emulsion layer within the extractor drum. Simultaneously, to enhance the mixing effect, the user can start the motor, causing the stirring plate at the bottom of the mixing tank to rotate. This rotation of the stirring plate accelerates the flow rate of the washing liquid within the mixing tank, speeding up the mixing of the washing liquid with the demulsifier in the storage cylinder.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1-4 According to one embodiment of the present invention, a centrifugal extraction device includes a storage cylinder 201, a plurality of storage cylinders 201 are symmetrically arranged in a mixing tank 101, and the storage cylinders 201 are symmetrically provided with longitudinal through grooves, and sealing plates 202 are correspondingly provided on the through grooves. The sealing plates 202 are rotatably connected to the storage cylinders 201 and are tightly fitted to the storage cylinders 201. A stirring plate 203 is rotatably connected to the bottom of the mixing tank 101, and a plurality of stirring plates are provided on the stirring plate 203.

[0016] It also includes a limiting component for allowing the storage cylinder 201 to rotate relative to the sealing plate 202; and a feeding component for adding solid demulsifier into the storage cylinder 201.

[0017] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sealing plate 202 described in the above embodiments. For example, the sealing plate 202 is attached to the arc surface of the storage cylinder 201 and is provided with a sealing film. The purpose of this arrangement is to increase the sealing effect of the sealing plate 202 on the storage cylinder 201. In addition, the mixing tank 101 is provided with a longitudinally transparent side plate with a scale strip on it, so as to facilitate the observation of the liquid level in the mixing tank 101.

[0018] Specifically, the bottom of the stirring plate 203 is fixedly connected to the output shaft of the motor 301, the motor 301 is fixedly connected to the mixing tank 101, and the two sides of the mixing tank 101 are fixedly connected to the flow pipes 307, and each flow pipe 307 is equipped with a valve.

[0019] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific flow tube 307 described in the above embodiments. For example, both flow tubes 307 can be nested with flexible tubes to inject washing liquid into the mixing tank 101 and to discharge the washing liquid from the mixing tank 101 after mixing with the demulsifier.

[0020] Specifically, the limiting component includes a gear 206 and a gear ring 207. The gear 206 is fixedly connected to the storage cylinder 201, and multiple gears 206 are located on the same circumference. Any gear 206 is meshed with the gear ring 207.

[0021] And auxiliary components for limiting the rotation of the storage cylinder 201, and drive components for periodically contacting the gear ring 207 with multiple gears 206.

[0022] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific gear ring 207 described in the above embodiments. For example, the length of the gear ring 207 should only be able to support the gear 206 to rotate 90°. The purpose of this setting is to avoid the gear 206 from rotating too much and causing the through grooves on both sides of the storage cylinder 201 to be blocked by the sealing plate 202.

[0023] Specifically, the auxiliary component includes a frame 204, which is fixedly connected to the inner wall of the mixing tank 101, and the storage cylinder 201 is rotatably connected to the frame 204. The frame 204 is fixedly connected to the sealing plate 202, and a through groove 205 is provided at the axis of the storage cylinder 201.

[0024] Specifically, the drive assembly includes a connecting block 208 and a motor A209. The connecting block 208 is fixedly connected to the gear ring 207 and is also fixedly connected to the output shaft of the motor A209. The motor A209 is fixedly connected to the frame 204, and a plurality of gears 206 surround the motor A209.

[0025] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motor A209 described in the above embodiments. For example, the motor A209 should be a motor with a self-locking effect. The purpose of this setting is to facilitate the increase of the limiting effect on the connecting block 208 through this setting, so as to prevent the output shaft from reversing if an external force is applied to it after the machine stops.

[0026] Specifically, the feeding assembly includes a guide pipe 303 and a flared pipe 304. The guide pipe 303 is located above the through groove 205, and the outer diameter of the guide pipe 303 is smaller than the inner diameter of the through groove 205. The flared pipe 304 is fixedly connected to the top of the guide pipe 303.

[0027] It also includes a positioning component for rotating and guiding the flow guide tube 303.

[0028] Specifically, the guide pipe 303 is fixedly connected to the cover plate 302, the cover plate 302 is rotatably connected to the top of the mixing tank 101, and a damping rubber ring is provided at the connection between the cover plate 302 and the mixing tank 101.

[0029] Specifically, the positioning component includes a positioning rod 305 and an indicator disk 306. The positioning rod 305 is fixedly connected to the cover plate 302, and the central axis of the positioning rod 305 is in the same vertical plane as any of the storage cylinders 201. The indicator disk 306 is fixedly connected to the cover plate 302, and the multiple grooves on the indicator disk 306 correspond to the multiple storage cylinders 201.

[0030] In this embodiment of the invention, the user adds solid demulsifier to the corresponding storage cylinder 201 through the flared tube 304. Since the sealing plate 202 blocks the grooves on both sides of the storage cylinder 201, the demulsifier can accumulate in the storage cylinder 201. When the amount of demulsifier added reaches the preset amount, the user should rotate the cover plate 302, causing the guide tube 303 to rotate synchronously around the mixing tank 101 until the positioning rod 305 is aligned with the second groove on the indicator plate 306. At this point, the flared tube 304 is above the second storage cylinder 201. Because the outer diameter of the guide tube 303 is smaller than the inner diameter of the through groove 205, it effectively prevents the demulsifier from falling outside the storage cylinder 201 when poured. The user then repeats this process until the same amount of demulsifier is added to all storage cylinders 201. At this point, the user can pour washing liquid into the mixing tank 101 through the flow tube 307 on one side. When the washing liquid is level with the top of the storage cylinder 201, the user can close the flow tube 307. When the valve is opened, the user can start the motor A209, causing the connecting block 208 fixedly connected to the output shaft of the motor A209 to rotate in a circular motion within the mixing tank 101. Since the gear ring 207 meshes with the gear 206, the gear ring 207 rotates at a constant speed, causing the storage cylinder 201 fixedly connected to its inner wall to rotate relative to the sealing plate 202. This causes the grooves on both sides of the storage cylinder 201 to rotate out of the sealing range of the sealing plate 202. At this point, the demulsifier in the storage cylinder 201 begins to contact the washing liquid, thus preparing a mixture with a certain concentration to prevent the washing liquid from producing an emulsion layer within the extractor drum. Simultaneously, to enhance the mixing effect, the user can start the motor 301, causing the stirring plate 203 at the bottom of the mixing tank 101 to rotate. This rotation of the stirring plate 203 accelerates the flow rate of the washing liquid within the mixing tank 101, speeding up the mixing of the washing liquid with the demulsifier in the storage cylinder 201.

[0031] After the demulsifier and washing liquid are completely mixed, the user can drain the mixture through the channel 205 on the other side of the mixing tank 101. Then, the user can refill the washing liquid into the mixing tank 101 and continue to start the motor A209. At this time, the gear ring 207 contacts the second gear 206 during rotation, thereby driving the storage cylinder 201 to start rotating, so that the demulsifier and washing liquid inside come into contact with each other to circulate and mix the mixture, thereby ensuring that the supply of the mixture is sufficient for the use of the extraction machine.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0033] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0034] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0035] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0036] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0037] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
